by:Jxforklift     2022-01-23
For the maintenance of the carbon brushes of electric forklifts, the entire working surface of the carbon brushes of the forklifts should be in contact with the commutator surface. The surface of the forklift carbon brush should be as smooth as a mirror. Before operation, the working surface of the newly installed brush must be ground to meet the requirements of the commutator surface.   If there are only a few electric brush working surfaces that need to be ground, fine-grained glass sandpaper can be placed between the forklift carbon brush and the forklift commutator. (Rough face to the carbon brush), push the sandpaper back and forth to grind. If the working surface of a large number or all the carbon brushes needs to be grind, you can use a fine-grained glass sandpaper belt (the width of the belt is equal to the length of the forklift commutator) to wrap the reversing The surface of the forklift and the tail end of the sandpaper overlap each other, or the direction of overlap is the same as the normal rotation direction of the forklift motor.  Then rotate the armature according to the normal screwing direction of the forklift motor, and grind the working surface of the brush until all working surfaces of the brush are finished. At the same time, it is forbidden to use a grinding wheel or emery paper to grind the working surface of the forklift carbon brush, so as to avoid the emery particles falling into the carbon brush and scratching the forklift commutator, which may cause sparks inside the forklift motor.  The use of forklift carbon brushes. After the carbon brush is polished, remove the toner on the forklift commutator, and use dry compressed air to carefully blow off the forklift motor. However, it must be noted that the toner should not be blown into the forklift motor. After the forklift carbon brush is polished, the forklift motor should be used to run under light load (1/4-1/2 rated load) until the contact surface becomes a mirror surface. When the forklift carbon brushes/brushes are worn out and cannot be used, they must be replaced with spare parts of the same brand.
